HOG OILER.

Specification of Letters Patent:

Patented Feb. is, raw.

To all whom it may concern.

Be it known that I, CrrARLns ALFRED Cox, a citizen of the United States, and a resident. of Quincy,.in the countyof Adams and' State of Illino1s, have invented an improvement in Hog-Oilers, of which the following is a specification.

My invention is an improvement in hog oilers, and has for its object to provide a device of the character specified, by means of which oil, disinfectant, insecticide, or the like, may be applied to the hog automatically during the operation of scratching, and wherein valve mechanism is provided for controlling the flow of the oil or the like, having operative mechanism directly engaged by the body of the hog to open the valves.

In the drawings:

Figure 1 is a side elevation of the hog oiler with parts in section.

Fig. 2 is a partial vertical section.

Fig. 3 is a cross section on the line 3-3 of Fig. 1.

In the present embodiment of the invention a tank or reservoir 1 is provided for containing the oil or other material to be applied, the said reservoir having a handled cover 2, for closing the same.

The tank or reservoir is supported by a standard 3, which extends downwardly from one side of the reservoir, and this standard at its lower end rests upon a plate 47 of wood or the like, forming a base for the oiler as a whole.

The tank or reservoir has an outlet opening 5 at its bottom and at the opposite side from the standard 3, and a pipe 6, having an approximately square cross section is connected with the tank or reservoir at the opening.

This pipe 6 has a marginal flange 7, which fits against the tank, and the flange is secured to the tank by bolts and nuts 8. At its lower end the pipe or casing 6 has a flange 9 which rests upon the base, and the said flange is secured to the base by screw bolts 10 or the like. The pipe or casing 6 is inclined at an angle of approximately 45 with respect to the base, and the upper end is bent to fit against the tank or reser- V011.

1A partition 11 is arranged transversely of the bore of the pipe near the lower end,

and above this partition series of ports 12 are, provided, a series being provided at each face of the pipe or casing 6.

Each of these ports is in theform of an internally threaded nipple, and a valve casing 13 is threaded into each port.

Each of the valve casings has a bore for receiving the stem 14 of a valve 15, which normally closes the inner end of the valve casing 13. The inner end of each valve casing has a tapered seat, and the outer surface of each valve is shaped to fit the seat. Thus when the valves are held closed on their seats the flow of the oil or other liquid through the ports is prevented. When the valves are open, however, the oil or other liquid may pass out through the port of the casing through the longitudinally extending grooves 16 in the stems 14, and it will be noticed that the said stems 14 extend beyond the outer ends of the valve casings and form projections against which the hog may scratch or rub itself.

Each valve is normally held closed by a coil spring 17 which fits at one end around an extension on the inner face of the valve, and at the other around a lug on the wall of the pipe casing 6. The springs normally hold the valves closed, but when the hog rubs against the stems, they will be forced inward permitting'the oil or liquid to flow through the grooves 16. It will be noticed from an inspection of Figs. 1 and 2 that the casing 6 is provided with pockets 18 below the partition 11, on the outer face of the said pipe.

The pipe or casing assists in supporting the reservoir, forming an inclined brace, and it will be evident that when the animal rubs against the extensions of the stems 14: the valves will be opened, and the oil will flow out through the grooves 16 directly onto the coat of the hog. The lugs on the casing wall and on the valve present displacement of the springs. Whenever the pressure is relaxed on the stems the springs will immediately close the valves.

As a rule, devices of this character have a vertical rubbing member, so that the top of the back of the hog cannot be oiled. With the present invention, however, the rubbing post or member is inclined, so that the hog can rub its back against the post, thus permitting every part of the hog to tion and having a series of ports in each face, a valve casing threaded into each port, a valve cooperating with the inner end of each casing and having a stem extending through the casing and fitting the same closely and provided With longitudinally extending grooves, and a spring normally holding each valve closed and'within the casing.

be oiled. In addition the valve and the valve mechanism are at the point Where the animal rubs.

The pockets 18 catch any oil'that may Oopies of this patent may be obtained for five cents each, by addressing the Commissioner of Patents,
